Embodiment Construction
[0021] The elastic telescopic mechanism is formed by the spring 1 and the telescopic mechanism 8, and the oil cylinder 2 is connected with the telescopic mechanism 8 to form a rolling brush control mechanism, and the rolling brush drag frame 9 is installed at the rear of the automobile.
[0022] When the car is running and does not clear the snow, the oil cylinder 2 shrinks. Since the upper end of the telescopic mechanism 8 is fixed on the roller brush drag frame 9 through the A pin 7, the oil cylinder 2 connected with the telescopic mechanism 8 is fixed through the B pin 6. Pulling the brush holder 5 makes the brush holder 5 move upward around the brush holder shaft 3, thereby lifting the roller brush away from the road surface.
[0023] When the car is running and performing snow removal operations, the oil cylinder 2 is extended, so that the brush holder 5 moves downward around the brush holder shaft 3, thereby putting the roller brush on the road.
